DETAILED DESCRIPTION

[0023] The first embodiment of this application is:

[0024] See also Figure 1-Figure 3 ,in, Figure 1 This is a schematic diagram of the overall structure of the first embodiment of the present invention. Figure 2 This is a side view of the entire first embodiment of the present utility model. Figure 3 It is an overall top view of the first embodiment of the present utility model.

[0025] The utility model provides a multi-level truck frame including a support rod 101 and a retractable assembly 102. The retractable assembly 102 includes a side rod 103, a first cross rod 104, a connecting member 105, a second cross rod 106, a fixing rod 107, a sliding member 108, a fixing member 109, a connecting rod 110, a mounting member 111, a connecting bolt 112, a first storage plate 113 and a second storage plate 114. The above-mentioned solution solves the problem that after the existing box truck automatically adjusts the three-dimensional shelf to retract the rectangular frame, the overall frame occupancy range remains unchanged, which causes inconvenience in loading large goods in the car.

[0026] According to this specific embodiment, a plurality of the support rods 101 are included, and the truck frame expands the range of storage. The pressure is distributed through the plurality of support rods 101 assemblies, thereby achieving stable support.

[0027] The side rod 103 is fixedly connected to the support rod 101 and is located on one side of the support rod 101. The first cross bar 104 is rotatably connected to the support rod 101 and is located on one side of the support rod 101. The connecting piece 105 is rotatably connected to the first cross bar 104 and is located on one side of the first cross bar 104. One end of the second cross bar 106 is rotatably connected to the connecting rod 110, and the other end is fixedly connected to the support rod 101 and is located on one side of the connecting piece 105. The fixing rod 107 is rotatably connected to the connecting rod 110, and the other end is fixedly connected to the support rod 101 and is located on one side of the connecting piece 105. The connecting member 105 is fixedly connected and located on one side of the connecting member 105. The sliding member 108 is slidably connected to the fixing rod 107 and is located on one side of the fixing rod 107. The fixing member 109 is fixedly connected to the sliding member 108 and is located on one side of the sliding member 108. One end of the connecting rod 110 is rotatably connected to the fixing member 109, and the other end is fixedly connected to the support rod 101 and is located on one side of the fixing member 109. The multiple support rods 101 are connected through the side rods 103 and the first cross bar 104. The connecting member 105 and the second cross bar 106 are connected to form a rectangle, wherein the first cross bar 104 and the connecting member 105 and the second cross bar 106 and the connecting member 105 are rotatably connected and can be adjusted during contraction. The fixed rod 107 is fixed to the surface of the connecting member 105, and the sliding member 108 can slide on the fixed rod 107. The two connecting rods 110 are restricted by the fixed member 109 on the surface of the sliding member 108, and the connecting rod 110 is in contact with the fixed member 109. One end of the connecting rod 110 can be rotated, and the other end is connected to the support rod 101 and is fixed. When the frame is not in use and needs to be retracted, the sliding member 108 is slid upward. The sliding of the sliding member 108 will cause one end of the connecting rod 110 to rotate on the fixing member 109, thereby driving the support rods 101 on both sides to gather together. At the same time, the first cross bar 104 and the second cross bar 106 inside are bent and folded based on the connecting rod 110, thereby achieving contraction. By gathering and shrinking the entire vehicle, the space occupied by the electric truck compartment is reduced.

[0028] Secondly, the mounting member 111 is fixedly connected to the fixing rod 107 and is located on one side of the fixing rod 107. The connecting bolt 112 passes through the sliding member 108 and is threadedly connected to the mounting member 111 and is located on one side of the mounting member 111. The sliding member 108 has two gears when sliding on the fixing rod 107. When it is at the top of the fixing rod 107, the support rods 101 on both sides are gathered to shrink. When it is at the bottom of the fixing rod 107, it is supported and limited by the connecting rod 110 to expand it to form a storage platform. The mounting member 111 is provided at the two gears. When the required gear is reached, the connecting bolt 112 is passed through the fixing rod 107 and is threadedly tightened with the mounting member 111 to achieve the effect of shrinkage and support.

[0029] At the same time, the first storage plate 113 is fixedly connected to the first cross bar 104 and is located on one side of the first cross bar 104. The second storage plate 114 is fixedly connected to the second cross bar 106 and is located on one side of the second cross bar 106. The first storage plate 113 and the second storage plate 114 are respectively installed in the blank space between the first cross bar 104 and the second cross bar 106. The first storage plate 113 and the second storage plate 114 are used as platforms for placing items, and one end of the first storage plate 113 and the second storage plate 114 is arc-shaped, which is more convenient when folding and shrinking.

[0030] When using the present invention, loosen the connecting bolt 112 so that the sliding member 108 can slide up and down on the fixing rod 107. The sliding of the sliding member 108 will drive the connecting rod 110 to gather and expand. When shrinking, the connecting rod 110 is pushed upward. One end of the connecting rod 110 rotates on the fixing member 109, thereby driving the support rod 101 at the other end to gather toward the middle. During the gathering process, the first cross bar 104 and the second cross bar 106 are also folded based on the connecting member 105. The folding of the first cross bar 104 and the second cross bar 106 will drive the first storage plate 113 and the second support plate to overlap and fold. Finally, the connecting bolt 112 is passed through the sliding member 108 and is threadedly connected and fixed with the corresponding mounting member 111. The whole is disassembled and broken down into parts to reduce the space occupied in the compartment of the electric truck, so that large items can be placed in the compartment space of the electric truck.

[0031] The second embodiment of this application is:

[0032] Based on the first embodiment, please refer to Figure 4-Figure 5 ,in, Figure 4 This is a schematic diagram of the overall structure of the second embodiment of the present invention. Figure 5 This is a schematic structural diagram of the second embodiment of the present invention when multi-layer assembly is performed as a whole. The multi-layer truck frame provided by the present invention further includes a mounting assembly 203 , and the mounting assembly 203 includes an insert rod 201 and a fixing bolt 202 .

[0033] For this specific embodiment, the insertion rod 201 is fixedly connected to the support rod 101 and is located on one side of the support rod 101. The fixing bolt 202 passes through the support rod 101 and is threadedly connected to the insertion rod 201, and is located on one side of the support rod 101. The frame can be connected in multiple layers. By inserting the insertion rod 201 at the bottom of the support rod 101 into the top of another support rod 101, and then passing the fixing bolt 202 through the support rod 101 to threadably connect and lock the internal insertion rod 201, height adjustment can be achieved. Multi-layer frames can be installed in the carriage of the electric truck as needed.

[0034] When using the present invention, the fixing bolt 202 is loosened, the insertion rod 201 is taken out from the top of the support rod 101 in turn, and then the connecting bolt 112 is loosened, so that the sliding member 108 can slide up and down on the fixing rod 107. The sliding of the sliding member 108 drives the connecting rod 110 to gather and expand. When shrinking, the connecting rod 110 is pushed upward. One end of the connecting rod 110 rotates on the fixing member 109, thereby driving the support rod 101 at the other end to gather toward the middle. In the process of gathering, the first cross bar 104 and the second cross bar 106 are also folded based on the connecting member 105. The folding of the first cross bar 104 and the second cross bar 106 will drive the first storage plate 113 and the second support plate to overlap and fold. Finally, the connecting bolt 112 is passed through the sliding member 108 and is threadedly connected and fixed with the corresponding mounting member 111. The whole is disassembled and broken down into pieces to reduce the space occupied by the electric truck compartment, and large items can be placed in the electric truck compartment space.

[0035] The third embodiment of this application is:

[0036] Based on the second embodiment, please refer to Figure 6-Figure 7 ,in, Figure 6 This is a schematic diagram of the overall structure of the third embodiment of the present invention. Figure 7 It is an overall side view of the third embodiment of the present invention. The multi-layer truck frame provided by the present invention further includes a fixing assembly 301 , and the fixing assembly 301 includes a mounting seat 302 and a suction cup 303 .

[0037] According to this specific embodiment, the mounting seat 302 is fixedly connected to the support rod 101 and is located on one side of the support rod 101. The suction cup 303 is fixedly connected to the mounting seat 302 and is located on one side of the mounting seat 302. When the frame is used for placing objects, the vehicle will shake while driving, which may cause the frame to collapse. The mounting seat 302 is fixed to the bottom of the support rod 101, and the suction cup 303 is installed on the mounting seat 302. The suction cup 303 sucks the car body to achieve a fixing effect, thereby preventing collapse caused by shaking during driving.

[0038] When using the present invention, the suction cups 303 at the four corners are pulled out from the carriage, and the fixing bolts 202 are loosened to remove the insertion rods 201 from the top of the support rods 101 in turn. Then, the connecting bolts 112 are loosened to allow the sliding member 108 to slide up and down on the fixing rod 107. The sliding of the sliding member 108 drives the connecting rod 110 to gather and expand, and pushes the connecting rod 110 upward when shrinking. One end of the connecting rod 110 rotates on the fixing member 109 to drive the other end of the connecting rod 110 to move upward. The support rods 101 are gathered toward the middle, and during the gathering process, the first cross bar 104 and the second cross bar 106 are also folded based on the connecting member 105. The folding of the first cross bar 104 and the second cross bar 106 will drive the first storage plate 113 and the second storage plate 114 to overlap and fold. Finally, the connecting bolt 112 is passed through the sliding member 108 and is threadedly connected and fixed to the corresponding mounting member 111. The whole is disassembled and broken down into parts to reduce the occupied space, so that large items can be placed in the compartment space of the electric truck.
